If you're a company that's going to "drive a new approach to social networking and solve key problems holding back the advancement of the semantic web" shouldn't you make your OWN website.
That is the problem I have always had with website creators. If you're trying to do something technical you're going to be looked down upon for using them to make your site. If you were going to sell running shoes to people then yeah it's great, but I don't think Weebly has a plug-in to solve the problems of the Semantic Web.
On a related note, it seems to me that if you can "drive a new approach to social networking and solve key problems holding back the advancement of the semantic web," you ought to be able to create a site whose visual structure doesn't collapse entirely when the text is enlarged a few sizes? (apologies from a guy with 20/50 vision, pre-correction)
This metaphor doesn't work as well as it seems. Architecture firms don't personally build the buildings they design. It's probable that someone dealing with "the semantic web" and fitting in with "new media" companies actually should build websites.
Even if they're only working on the back-end solutions, having a poor website is more like an architecture firm having a terribly designed office which undermines the customer's confidence.
I suppose that could be true, but I really think it depends on what it is you're doing. If you're going to be doing something inventive in the backend, some sort of api, or db structure, then yeah I understand that. But I still think there are going to be people out there that look at the site with that stigma. Just something to be aware of.
